School discipline is the system of rules, punishments, and behavioral strategies appropriate to the regulation of children or adolescents and the maintenance of order in schools. Its aim is to control the students' actions and behavior.
An obedient student is in compliance with the school rules and codes of conduct. These rules may, for example, define the expected standards of clothing, timekeeping, social conduct, and work ethic. The term discipline is also applied to the punishment that is the consequence of breaking the rules. The aim of discipline is to set limits restricting certain behaviors or attitudes that are seen as harmful or going against school policies, educational norms, school traditions, et cetera...Theory
School discipline practices are generally informed by theory from psychologists and educators. There are a number of theories to form a comprehensive discipline strategy for an entire school or a particular class.
- Positive approach is grounded in teachers' respect for students. Instills in students a sense of responsibility by using youth/adult partnerships to develop and share clear rules, provide daily opportunities for success, and administer in-school suspension for noncompliant students. Based on Glasser's Reality Therapy. Research (e.g., Allen) is generally supportive of the PAD program.[1]
- Teacher effectiveness training differentiates between teacher-owned and student-owned problems, and proposes different strategies for dealing with each. Students are taught problem-solving and negotiation techniques. Researchers (e.g., Emmer and Aussiker) find that teachers like the programme and that their behaviour is influenced by it, but effects on student behaviour are unclear.[1]
- Adlerian approaches is an umbrella term for a variety of methods which emphasize understanding the individual's reasons for maladaptive behavior and helping misbehaving students to alter their behavior, while at the same time finding ways to get their needs met. Named for psychiatrist Alfred Adler. These approaches have shown some positive effects on self-concept, attitudes, and locus of control, but effects on behavior are inconclusive (Emmer and Aussiker). Not only were the statistics on suspensions and vandalism significant, but also the recorded interview of teachers demonstrates the improvement in student attitude and behaviour, school atmosphere, academic performance, and beyond that, personal and professional growth.

'A warning to would-be slackers, The Dropout shows the loneliness and frustration that develop in Robert, who drops out of school and tries to find a job before he is qualified to compete in the highly competitive world of modern work. Told in Davis' inimitable voiceover style, this film retells the classic "downward spiral" tale.
"More than ever before, competition is keen," says the narrator. "The work force is made up of skilled personnel." Attracted by the world of work and eager to leave the regulated society of high school behind, Robert begins to pound the Santa Monica pavement. But no one wants to hire a dropout. And, what's worse, his schoolmates seem to be getting along just fine without him. "There used to be an order in your life. You belonged. You had an anchor in a social institution. Now you feel adrift. You're on the outside, looking in," comments the narrator, who throughout the film addresses his words to Robert.
And that's not the end of it. Alice, Robert's girlfriend, has to meet him in secret, as her parents don't want her seeing a dropout. In an attempt to keep her, "you downgrade your image one more step and take a job as busboy." This improves things, but not for long, and one night Alice shows up at the restaurant with another date.
Robert begins to crash and burn. He cannot even get an unskilled job, as employers want an older, more reliable hand. "You begin to drift in earnest...much of your day is spent wandering aimlessly in the less desirable sections of town." He begins to frequent a pool hall, where men of all ages with "no competition, no drive, no illusion" hang out. When his friend Jake, an obvious lowlife, is arrested, he wonders how much unlike Jake he has become. "You wish you knew."
Rare among teenage transgression films in that there is no successful adult intervention to head off disaster, The Dropout seems to stress the devastating effects of shame and downward class mobility. Robert doesn't just leave the bustling, productive environment of high school for "the less desirable sections of town," he's also a traitor to the very ideas of industriousness and self-improvement. Perhaps this is one of the reasons his father "throws him out of bed before he leaves for work."

http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas
The indigenous peoples of the Americas are the pre-Columbian inhabitants of North and South America and their descendants. Pueblos indígenas (indigenous peoples) is a common term in Spanish-speaking countries. Aborigen (aboriginal/native) is used in Argentina, while "Amerindian" is used in Guyana, but not commonly used in other countries. Indigenous peoples are commonly known in Canada as Aboriginal peoples, which include First Nations, Inuit, and Métis peoples. Indigenous peoples of the United States are known as Native Americans or American Indians and Alaskan Natives.
According to a prevailing New World migration model, migrations of humans from Eurasia to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The most recent migration could have taken place around 12,000 years ago, with the earliest period remaining a matter of some unresolved contention. These early Paleo-Indians soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.
Application of the term "Indian" originated with Christopher Columbus, who thought that he had arrived in the East Indies, while seeking Asia. Later, the Americas came to be known as the "West Indies," a name still used today to refer to the Caribbean. The use of the names "Indies" and "Indian" has served to imply some kind of racial or cultural unity for the aboriginal peoples of the Americas. Once created, the unified "Indian" was codified in law, religion, and politics. The unitary idea of "Indians" was not originally shared by indigenous peoples, but many over the last two centuries have embraced the identity. The term "Indian" does not include Aleuts, Inuit, or Yupik peoples.
While some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in Amazonia, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time and work in reshaping and cultivating the flora indigenous to the Americas. Some societies depended heavily on agriculture while others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires.
Many parts of the Americas are still populated by indigenous Americans; some countries have sizable populations, especially Bolivia, Peru, Mexico, Guatemala, Belize, Colombia, Ecuador, and Greenland. At least a thousand different indigenous languages are spoken in the Americas. Some, such as Quechua languages, Aymara, Guaraní, Mayan languages, and Nahuatl, count their speakers in millions. Many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization and subsistence practices. Some indigenous peoples still live in relative isolation from Western society, and a few are still counted as uncontacted peoples...

The Archives were founded by Rick Prelinger in 1982 in order to preserve what he calls "ephemeral" films: films sponsored by corporations and organizations, educational films, and amateur and home movies. Typically, ephemeral films were produced to fulfill specific purposes at specific times, and many exist today only by chance or accident. About 65% of the Archive's holdings are in the public domain because their copyrights have expired, or because they were U.S. productions that were published without proper copyright notice.

The stated goal of the Prelinger Archives is to "collect, preserve, and facilitate access to films of historic significance that haven't been collected elsewhere."

By 2001, it had acquired 60,000 completed films of varying lengths and over 30,000 cans of unedited film. In 2002, the Library of Congress acquired the physical films held in the Archives as of that date; the Archives made two subsequent donations to Library of Congress totalling some 65,000 cans of film, primarily industrial and educational titles. As of spring 2015, the Archives holds about 8,000 films in videotape and digital form, approximately 14,000 home movies, and 1,000 industrial and sponsored films acquired since 2002.

Archive

An archive is an accumulation of historical records or the physical place they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity.

In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost always unique, unlike books or magazines for which many identical copies exist. This means that archives are quite distinct from libraries with regard to their functions and organization, although archival collections can often be found within library buildings.

Francisco

Francisco is the Spanish and Portuguese form of the masculine given name Franciscus (corresponding to English Francis).

In Spanish, people with the name Francisco sometimes are nicknamed "Paco": San Francisco de Asís was known as Pater Comunitatis (The Community father) when he founded the Franciscan order, "Paco" is a short form of "Pater Comunitatis". Also, in Spanish Latin America and in the Philippines, people with the name Francisco are called "Pancho". "Kiko" is also used as a nickname in the Philippines.

In Portuguese, people named Francisco are commonly nicknamed "Chico" (shíco) or "Kiko". This is also a less-common nickname for Francisco in Spanish too.

People with the given name

Pope Francis is rendered in the Spanish and Portuguese languages as Papa Francisco

Coral Reefs: "Coral Wonderland" (circa 1950) Prelinger Archives

"Underwater oceanic footage of various kinds of fish and other aquatic creatures swimming in and around the coral reef. Sea slugs, octopi, coral, feathered starfish, shellfish, box fish, king snapper, butterfly cod, sea anemones, hermit crabs, sea turtles."
http://en.wikipedia.org/wiki/Coral_reef
Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Reefs grow best in warm, shallow, clear, sunny and agitated waters.
Often called "rainforests of the sea", coral reefs form some of the most diverse ecosystems on Earth. They occupy less than 0.1% of the world's ocean surface, about half the area of France, yet they provide a home for 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians. Paradoxically, coral reefs flourish even though they are surrounded by ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water corals also exist on smaller scales in other areas.
Coral reefs deliver ecosystem services to tourism, fisheries and shoreline protection. The annual global economic value of coral reefs is estimated between US$29.8-375 billion. However, coral reefs are fragile ecosystems, partly because they are very sensitive to water temperature. They are under threat from climate change, oceanic acidification, blast fishing, cyanide fishing for aquarium fish, sunscreen use, overuse of reef resources, and harmful land-use practices, including urban and agricultural runoff and water pollution, which can harm reefs by encouraging excess algal growth...Formation
Most of the coral reefs we can see today were formed after the last glacial period when melting ice caused the sea level to rise and flood the continental shelves. This means that most modern coral reefs are less than 10,000 years old. As communities established themselves on the shelves, the reefs grew upwards, pacing rising sea levels. Reefs that rose too slowly could become drowned reefs. They are covered by so much water that there was insufficient light. Coral reefs are found in the deep sea away from continental shelves, around oceanic islands and as atolls. The vast majority of these islands are volcanic in origin. The few exceptions have tectonic origins where plate movements have lifted the deep ocean floor on the surface...
The approximately 20,000 year old Great Barrier Reef offers an example of how coral reefs formed on continental shelves. Sea level was then 120 m (390 ft) lower than in the 21st century. As sea level rose, the water and the corals encroached on what had been hills of the Australian coastal plain. By 13,000 years ago, sea level had risen to 60 m (200 ft) lower than at present, and many hills of the coastal plains had become continental islands. As the sea level rise continued, water topped most of the continental islands. The corals could then overgrow the hills, forming the present cays and reefs...
Healthy tropical coral reefs grow horizontally from 1 to 3 cm (0.39 to 1.2 in) per year, and grow vertically anywhere from 1 to 25 cm (0.39 to 9.8 in) per year; however, they grow only at depths shallower than 150 m (490 ft) because of their need for sunlight, and cannot grow above sea level.
Materials
As the name implies, the bulk of coral reefs is made up of coral skeletons from mostly intact coral colonies... shell fragments and the remains of calcareous algae such as the green-segmented genus Halimeda can add to the reef's ability to withstand damage from storms and other threats. Such mixtures are visible in structures such as Eniwetok Atoll...

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.
The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes, and gravitational waves...
Special relativity
Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of MovingBodies" (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics:
- The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity).
- The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.
...the theory has many surprising and counterintuitive consequences. Some of these are:
- Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.
- Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock.
- Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer.
- Maximum speed is finite: No physical object, message or field line can travel faster than the speed of light in a vacuum...
- Mass–energy equivalence: E = mc2, energy and mass are equivalent and transmutable...
The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. (See Maxwell's equations of electromagnetism).
General relativity
General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example, when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and any momentum within it.
Some of the consequences of general relativity are:
- Clocks run slower in deeper gravitational wells. This is called gravitational time dilation...
- Rays of light bend in the presence of a gravitational field.
- Rotating masses "drag along" the spacetime around them; a phenomenon termed "frame-dragging".
- The universe is expanding, and the far parts of it are moving away from us faster than the speed of light...

School discipline is the system of rules, punishments, and behavioral strategies appropriate to the regulation of children or adolescents and the maintenance of order in schools. Its aim is to control the students' actions and behavior.
An obedient student is in compliance with the school rules and codes of conduct. These rules may, for example, define the expected standards of clothing, timekeeping, social conduct, and work ethic. The term discipline is also applied to the punishment that is the consequence of breaking the rules. The aim of discipline is to set limits restricting certain behaviors or attitudes that are seen as harmful or going against school policies, educational norms, school traditions, et cetera...Theory
School discipline practices are generally informed by theory from psychologists and educators. There are a number of theories to form a comprehensive discipline strategy for an entire school or a particular class.
- Positive approach is grounded in teachers' respect for students. Instills in students a sense of responsibility by using youth/adult partnerships to develop and share clear rules, provide daily opportunities for success, and administer in-school suspension for noncompliant students. Based on Glasser's Reality Therapy. Research (e.g., Allen) is generally supportive of the PAD program.[1]
- Teacher effectiveness training differentiates between teacher-owned and student-owned problems, and proposes different strategies for dealing with each. Students are taught problem-solving and negotiation techniques. Researchers (e.g., Emmer and Aussiker) find that teachers like the programme and that their behaviour is influenced by it, but effects on student behaviour are unclear.[1]
- Adlerian approaches is an umbrella term for a variety of methods which emphasize understanding the individual's reasons for maladaptive behavior and helping misbehaving students to alter their behavior, while at the same time finding ways to get their needs met. Named for psychiatrist Alfred Adler. These approaches have shown some positive effects on self-concept, attitudes, and locus of control, but effects on behavior are inconclusive (Emmer and Aussiker). Not only were the statistics on suspensions and vandalism significant, but also the recorded interview of teachers demonstrates the improvement in student attitude and behaviour, school atmosphere, academic performance, and beyond that, personal and professional growth.
- Appropriate school learning theory and educational philosophy is a strategy for preventing violence and promoting order and discipline in schools, put forward by educational philosopher Daniel Greenberg and practised by the Sudbury Valley School...

'A warning to would-be slackers, The Dropout shows the loneliness and frustration that develop in Robert, who drops out of school and tries to find a job before he is qualified to compete in the highly competitive world of modern work. Told in Davis' inimitable voiceover style, this film retells the classic "downward spiral" tale.
"More than ever before, competition is keen," says the narrator. "The work force is made up of skilled personnel." Attracted by the world of work and eager to leave the regulated society of high school behind, Robert begins to pound the Santa Monica pavement. But no one wants to hire a dropout. And, what's worse, his schoolmates seem to be getting along just fine without him. "There used to be an order in your life. You belonged. You had an anchor in a social institution. Now you feel adrift. You're on the outside, looking in," comments the narrator, who throughout the film addresses his words to Robert.
And that's not the end of it. Alice, Robert's girlfriend, has to meet him in secret, as her parents don't want her seeing a dropout. In an attempt to keep her, "you downgrade your image one more step and take a job as busboy." This improves things, but not for long, and one night Alice shows up at the restaurant with another date.
Robert begins to crash and burn. He cannot even get an unskilled job, as employers want an older, more reliable hand. "You begin to drift in earnest...much of your day is spent wandering aimlessly in the less desirable sections of town." He begins to frequent a pool hall, where men of all ages with "no competition, no drive, no illusion" hang out. When his friend Jake, an obvious lowlife, is arrested, he wonders how much unlike Jake he has become. "You wish you knew."
Rare among teenage transgression films in that there is no successful adult intervention to head off disaster, The Dropout seems to stress the devastating effects of shame and downward class mobility. Robert doesn't just leave the bustling, productive environment of high school for "the less desirable sections of town," he's also a traitor to the very ideas of industriousness and self-improvement. Perhaps this is one of the reasons his father "throws him out of bed before he leaves for work."

http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas
The indigenous peoples of the Americas are the pre-Columbian inhabitants of North and South America and their descendants. Pueblos indígenas (indigenous peoples) is a common term in Spanish-speaking countries. Aborigen (aboriginal/native) is used in Argentina, while "Amerindian" is used in Guyana, but not commonly used in other countries. Indigenous peoples are commonly known in Canada as Aboriginal peoples, which include First Nations, Inuit, and Métis peoples. Indigenous peoples of the United States are known as Native Americans or American Indians and Alaskan Natives.
According to a prevailing New World migration model, migrations of humans from Eurasia to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The most recent migration could have taken place around 12,000 years ago, with the earliest period remaining a matter of some unresolved contention. These early Paleo-Indians soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.
Application of the term "Indian" originated with Christopher Columbus, who thought that he had arrived in the East Indies, while seeking Asia. Later, the Americas came to be known as the "West Indies," a name still used today to refer to the Caribbean. The use of the names "Indies" and "Indian" has served to imply some kind of racial or cultural unity for the aboriginal peoples of the Americas. Once created, the unified "Indian" was codified in law, religion, and politics. The unitary idea of "Indians" was not originally shared by indigenous peoples, but many over the last two centuries have embraced the identity. The term "Indian" does not include Aleuts, Inuit, or Yupik peoples.
While some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in Amazonia, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time and work in reshaping and cultivating the flora indigenous to the Americas. Some societies depended heavily on agriculture while others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires.
Many parts of the Americas are still populated by indigenous Americans; some countries have sizable populations, especially Bolivia, Peru, Mexico, Guatemala, Belize, Colombia, Ecuador, and Greenland. At least a thousand different indigenous languages are spoken in the Americas. Some, such as Quechua languages, Aymara, Guaraní, Mayan languages, and Nahuatl, count their speakers in millions. Many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization and subsistence practices. Some indigenous peoples still live in relative isolation from Western society, and a few are still counted as uncontacted peoples...

"Underwater oceanic footage of various kinds of fish and other aquatic creatures swimming in and around the coral reef. Sea slugs, octopi, coral, feathered starfish, shellfish, box fish, king snapper, butterfly cod, sea anemones, hermit crabs, sea turtles."
http://en.wikipedia.org/wiki/Coral_reef
Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Reefs grow best in warm, shallow, clear, sunny and agitated waters.
Often called "rainforests of the sea", coral reefs form some of the most diverse ecosystems on Earth. They occupy less than 0.1% of the world's ocean surface, about half the area of France, yet they provide a home for 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians. Paradoxically, coral reefs flourish even though they are surrounded by ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water corals also exist on smaller scales in other areas.
Coral reefs deliver ecosystem services to tourism, fisheries and shoreline protection. The annual global economic value of coral reefs is estimated between US$29.8-375 billion. However, coral reefs are fragile ecosystems, partly because they are very sensitive to water temperature. They are under threat from climate change, oceanic acidification, blast fishing, cyanide fishing for aquarium fish, sunscreen use, overuse of reef resources, and harmful land-use practices, including urban and agricultural runoff and water pollution, which can harm reefs by encouraging excess algal growth...Formation
Most of the coral reefs we can see today were formed after the last glacial period when melting ice caused the sea level to rise and flood the continental shelves. This means that most modern coral reefs are less than 10,000 years old. As communities established themselves on the shelves, the reefs grew upwards, pacing rising sea levels. Reefs that rose too slowly could become drowned reefs. They are covered by so much water that there was insufficient light. Coral reefs are found in the deep sea away from continental shelves, around oceanic islands and as atolls. The vast majority of these islands are volcanic in origin. The few exceptions have tectonic origins where plate movements have lifted the deep ocean floor on the surface...
The approximately 20,000 year old Great Barrier Reef offers an example of how coral reefs formed on continental shelves. Sea level was then 120 m (390 ft) lower than in the 21st century. As sea level rose, the water and the corals encroached on what had been hills of the Australian coastal plain. By 13,000 years ago, sea level had risen to 60 m (200 ft) lower than at present, and many hills of the coastal plains had become continental islands. As the sea level rise continued, water topped most of the continental islands. The corals could then overgrow the hills, forming the present cays and reefs...
Healthy tropical coral reefs grow horizontally from 1 to 3 cm (0.39 to 1.2 in) per year, and grow vertically anywhere from 1 to 25 cm (0.39 to 9.8 in) per year; however, they grow only at depths shallower than 150 m (490 ft) because of their need for sunlight, and cannot grow above sea level.
Materials
As the name implies, the bulk of coral reefs is made up of coral skeletons from mostly intact coral colonies... shell fragments and the remains of calcareous algae such as the green-segmented genus Halimeda can add to the reef's ability to withstand damage from storms and other threats. Such mixtures are visible in structures such as Eniwetok Atoll...

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy.
The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes, and gravitational waves...
Special relativity
Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of MovingBodies" (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics:
- The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity).
- The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.
...the theory has many surprising and counterintuitive consequences. Some of these are:
- Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.
- Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock.
- Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer.
- Maximum speed is finite: No physical object, message or field line can travel faster than the speed of light in a vacuum...
- Mass–energy equivalence: E = mc2, energy and mass are equivalent and transmutable...
The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. (See Maxwell's equations of electromagnetism).
General relativity
General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example, when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and any momentum within it.
Some of the consequences of general relativity are:
- Clocks run slower in deeper gravitational wells. This is called gravitational time dilation...
- Rays of light bend in the presence of a gravitational field.
- Rotating masses "drag along" the spacetime around them; a phenomenon termed "frame-dragging".
- The universe is expanding, and the far parts of it are moving away from us faster than the speed of light...

http://en.wikipedia.org/wiki/Ford_N-Series_tractor
The Ford N-Series tractors were a series of farm tractors produced by Ford Motor Company between 1939 and 1952, spanning the 9N, 2N, and 8N models.
The 9N was the first American-made production-model tractor to incorporate Harry Ferguson's three-point hitch system, a design still used on most modern tractors today. It was released in October 1939. The 2N, introduced in 1942, was the 9N with some improved details. The 8N, which debuted in July 1947, was a largely new machine featuring more power and an improved transmission. It proved to be the most popular farm tractor of all time in North America...
The first genuine Ford tractor, called the Fordson tractor (because a misleading Ford brand not related to Henry Ford was squatting on the Ford name at the time), was a tremendous success in North America and Europe from 1917 to 1928. Ford of the U.S. left the tractor business in 1928. Ford Ltd of Britain continued thrive with the Fordson from 1928 onward. Some British Fordsons were imported to the U.S. during the following decade. Henry Ford continued tractor R&D in the U.S. after 1928...
In Ireland, businessman Harry Ferguson had been developing and selling various improved hitches, implements, and tractors since the 1910s. His first tractors were adapted from Model T cars. In 1920 and 1921 he gave demonstrations at Cork and Dearborn of his hitches and implements as aftermarket attachments to Fordson tractors. The hitches were mechanical at the time. By 1926, he and a team of longtime colleagues (including Willie Sands and ArchieGreer) had developed a good hydraulic three-point hitch. Ferguson put such hitches on Fordsons throughout the 1920s and early 1930s. In the mid-1930s, he had David Brown Ltd build Ferguson-brand tractors with his hitches and implements. In 1938, EberSherman, importer of Fordsons from England to the US and a friend of both Ford and Ferguson, arranged to have Ferguson demonstrate his tractor for Henry Ford...
Ford Motor Company invested $12 million in tooling to finance Ferguson's new distribution company. The investment resulted in the production of the 9N tractor which was introduced on June 29, 1939. It was officially called a "Ford tractor with the Ferguson system", although the name Ford-Ferguson was widely used. It sold for $585 including rubber tires, power take-off, Ferguson hydraulics, an electric starter, generator, and battery; lights were optional... The 9N weighed 2340 pounds and had 13 drawbar horsepower, which could pull a two-bottom plow. It was designed to be safe, quiet and easy to operate...
Approximately 750,000 9Ns were built, and it was estimated in 2001 that nearly half of these were still in regular use...
Official production of the 8N tractor began in July 1947. Equipped with a 4-speed transmission, this model was destined to become the top-selling individual tractor of all time in North America. The most noticeable differences between the 8N and its predecessors was the inclusion of a 4-speed transmission instead of a 3-speed in the 9N and 2N, and an increase in both PTO and drawbar horsepower. The other big change on the 8N was the addition of a 'Position-control' setting for the hydraulics...
https://en.wikipedia.org/wiki/Ford_3000
The Ford 3000 is a tractor that was introduced by Ford in the spring of 1965. It was part of Ford's Thousand Series of tractors. This was a "ground up" new platform designed to replace the "Prior" or "Hundred Series" Fords built from 1955 through 1964. It has a 3-cylinder OHV, water-cooled engine. It could be ordered with a Ford-built 158-cubic-inch gas or 175-cubic-inch diesel engine. It was rated at 37 horsepower at the PTO. Optional transmissions were a 4-speed, 6-speed (3-speed with high and low), 8-speed (4-seed with high and low) and a 10-speed 'Select O Speed' power shift transmission. Some of the available options were differential lock, power steering, Live PTO and hydraulic remote valves. Standard front tires were 5.5X16 and two options were available for the rear tires - either 13.6X28 or 14.9X24.

This was a "ground up" new platform designed to replace the "Prior" or "Hundred Series" Fords built from 1955 through 1964. It has a 3-cylinder OHV, water-cooled engine. It could be ordered with a Ford-built 158-cubic-inch gas or 175-cubic-inch diesel engine. It was rated at 37 horsepower at the PTO. Optional transmissions were a 4-speed, 6-speed (3-speed with high and low), 8-speed (4-seed with high and low) and a 10-speed 'Select O Speed' power shift transmission. Some of the available options were differential lock, power steering, Live PTO and hydraulic remote valves. Standard front tires were 5.5X16 and two options were available for the rear tires - either 13.6X28 or 14.9X24.

School discipline is the system of rules, punishments, and behavioral strategies appropriate to the regulation of children or adolescents and the maintenance of order in schools. Its aim is to control the students' actions and behavior.
An obedient student is in compliance with the school rules and codes of conduct. These rules may, for example, define the expected standards of clothing, timekeeping, social conduct, and work ethic. The term discipline is also applied to the punishment that is the consequence of breaking the rules. The aim of discipline is to set limits restricting certain behaviors or attitudes that are seen as harmful or going against school policies, educational norms, school traditions, et cetera...Theory
School discipline practices are generally informed by theory from psychologists and educators. There are a number of theories to form a comprehensive discipline strategy for an entire school or a particular class.
- Positive approach is grounded in teachers' respect for students. Instills in students a sense of responsibility by using youth/adult partnerships to develop and share clear rules, provide daily opportunities for success, and administer in-school suspension for noncompliant students. Based on Glasser's Reality Therapy. Research (e.g., Allen) is generally supportive of the PAD program.[1]
- Teacher effectiveness training differentiates between teacher-owned and student-owned problems, and proposes different strategies for dealing with each. Students are taught problem-solving and negotiation techniques. Researchers (e.g., Emmer and Aussiker) find that teachers like the programme and that their behaviour is influenced by it, but effects on student behaviour are unclear.[1]
- Adlerian approaches is an umbrella term for a variety of methods which emphasize understanding the individual's reasons for maladaptive behavior and helping misbehaving students to alter their behavior, while at the same time finding ways to get their needs met. Named for psychiatrist Alfred Adler. These approaches have shown some positive effects on self-concept, attitudes, and locus of control, but effects on behavior are inconclusive (Emmer and Aussiker). Not only were the statistics on suspensions and vandalism significant, but also the recorded interview of teachers demonstrates the improvement in student attitude and behaviour, school atmosphere, academic performance, and beyond that, personal and professional growth.
- Appropriate school learning theory and educational philosophy is a strategy for preventing violence and promoting order and discipline in schools, put forward by educational philosopher Daniel Greenberg and practised by the Sudbury Valley School...

'A warning to would-be slackers, The Dropout shows the loneliness and frustration that develop in Robert, who drops out of school and tries to find a job before he is qualified to compete in the highly competitive world of modern work. Told in Davis' inimitable voiceover style, this film retells the classic "downward spiral" tale.
"More than ever before, competition is keen," says the narrator. "The work force is made up of skilled personnel." Attracted by the world of work and eager to leave the regulated society of high school behind, Robert begins to pound the Santa Monica pavement. But no one wants to hire a dropout. And, what's worse, his schoolmates seem to be getting along just fine without him. "There used to be an order in your life. You belonged. You had an anchor in a social institution. Now you feel adrift. You're on the outside, looking in," comments the narrator, who throughout the film addresses his words to Robert.
And that's not the end of it. Alice, Robert's girlfriend, has to meet him in secret, as her parents don't want her seeing a dropout. In an attempt to keep her, "you downgrade your image one more step and take a job as busboy." This improves things, but not for long, and one night Alice shows up at the restaurant with another date.
Robert begins to crash and burn. He cannot even get an unskilled job, as employers want an older, more reliable hand. "You begin to drift in earnest...much of your day is spent wandering aimlessly in the less desirable sections of town." He begins to frequent a pool hall, where men of all ages with "no competition, no drive, no illusion" hang out. When his friend Jake, an obvious lowlife, is arrested, he wonders how much unlike Jake he has become. "You wish you knew."
Rare among teenage transgression films in that there is no successful adult intervention to head off disaster, The Dropout seems to stress the devastating effects of shame and downward class mobility. Robert doesn't just leave the bustling, productive environment of high school for "the less desirable sections of town," he's also a traitor to the very ideas of industriousness and self-improvement. Perhaps this is one of the reasons his father "throws him out of bed before he leaves for work."

http://en.wikipedia.org/wiki/Indigenous_peoples_of_the_Americas
The indigenous peoples of the Americas are the pre-Columbian inhabitants of North and South America and their descendants. Pueblos indígenas (indigenous peoples) is a common term in Spanish-speaking countries. Aborigen (aboriginal/native) is used in Argentina, while "Amerindian" is used in Guyana, but not commonly used in other countries. Indigenous peoples are commonly known in Canada as Aboriginal peoples, which include First Nations, Inuit, and Métis peoples. Indigenous peoples of the United States are known as Native Americans or American Indians and Alaskan Natives.
According to a prevailing New World migration model, migrations of humans from Eurasia to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The most recent migration could have taken place around 12,000 years ago, with the earliest period remaining a matter of some unresolved contention. These early Paleo-Indians soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.
Application of the term "Indian" originated with Christopher Columbus, who thought that he had arrived in the East Indies, while seeking Asia. Later, the Americas came to be known as the "West Indies," a name still used today to refer to the Caribbean. The use of the names "Indies" and "Indian" has served to imply some kind of racial or cultural unity for the aboriginal peoples of the Americas. Once created, the unified "Indian" was codified in law, religion, and politics. The unitary idea of "Indians" was not originally shared by indigenous peoples, but many over the last two centuries have embraced the identity. The term "Indian" does not include Aleuts, Inuit, or Yupik peoples.
While some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in Amazonia, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time and work in reshaping and cultivating the flora indigenous to the Americas. Some societies depended heavily on agriculture while others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires.
Many parts of the Americas are still populated by indigenous Americans; some countries have sizable populations, especially Bolivia, Peru, Mexico, Guatemala, Belize, Colombia, Ecuador, and Greenland. At least a thousand different indigenous languages are spoken in the Americas. Some, such as Quechua languages, Aymara, Guaraní, Mayan languages, and Nahuatl, count their speakers in millions. Many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization and subsistence practices. Some indigenous peoples still live in relative isolation from Western society, and a few are still counted as uncontacted peoples...

The Archives were founded by Rick Prelinger in 1982 in order to preserve what he calls "ephemeral" films: films sponsored by corporations and organizations, educational films, and amateur and home movies. Typically, ephemeral films were produced to fulfill specific purposes at specific times, and many exist today only by chance or accident. About 65% of the Archive's holdings are in the public domain because their copyrights have expired, or because they were U.S. productions that were published without proper copyright notice.

The stated goal of the Prelinger Archives is to "collect, preserve, and facilitate access to films of historic significance that haven't been collected elsewhere."

By 2001, it had acquired 60,000 completed films of varying lengths and over 30,000 cans of unedited film. In 2002, the Library of Congress acquired the physical films held in the Archives as of that date; the Archives made two subsequent donations to Library of Congress totalling some 65,000 cans of film, primarily industrial and educational titles. As of spring 2015, the Archives holds about 8,000 films in videotape and digital form, approximately 14,000 home movies, and 1,000 industrial and sponsored films acquired since 2002.
